Flow Chromatographs

FXi-2 Series 5 Inline Gas Chromatograph

The chromatograph is a stationary industrial device that includes a control station (industrial computer), electronic control units, a gas flow control unit (secondary sample preparation system), a sample dispensing device and an analytical unit consisting of a thermostat unit with detectors (up to two detectors) and chromatographic columns (up to eight columns).

The configuration of the complex (type and number of used detectors and chromatographic columns) depends on the nomenclature of the determined components.

To configure and diagnose the operation of the chromatograph, the LAMS software installed
on the built-in computer is used.

On the monitor screen, it is possible to display chromatograms in real time, save chromatograms, view current and archived results of measurements of the content of components, view and edit the parameters of the chromatograph.
